Title: Improvements in or relating to the regeneration of vulcanised rubber
IPC: C08J11/18
Filed: 1943-02-03
Abstract: Vulcanized rubber is regenerated by reducing it to finely-divided form and then subjecting it to mechanical treatment in the presence of a softening-agent, a peptising-agent, and an organic acid.  The vulcanized rubber is first reduced to a fine crumb by passing through grinding-rolls having a high differential speed ratio; the organic acid (benzoic acid or one of its substituted derivatives such as o-, m- or p-nitrobenzoic acid, the dinitrobenzoic acids or a halogen-substituted benzoic acid) and a neutral softening-agent (of hydroxylic or oxygen-containing character such as pine tar, pine oil, or coumarone resin) are added, the product being milled for a short period between rolls having a tight nip and a small differential speed ratio; the peptising-agent (an organic compound containing a mercapto group such as mercaptobenzthiazole or a - or b -naphthyl mercaptan) is then added, and the mixture subjected to mechanical working until a coherent sheet results.  The temperature is preferably maintained below 60 DEG  C. at least until the agents have been incorporated, when the mix may be raised to at least 100 DEG  C. and the working continued for a further period.  Suitable proportions are 0.5-3 per cent of acid, 2-10 per cent of softener, and 0.25-2 per cent of peptising-agent by weight of the vulcanized rubber.

Filed: 1941-02-10
Abstract: 544,293. Bale-tie fasteners. SIGNODE STEEL STRAPPING CO. Feb. 10, 1941, No. 1819. Convention date, Nov. 13, 1939. [Class 45] In a package-binding tool of the feed-wheel type whereby a loop of wire &c. encircling a package, &c. is tensioned by a rotatable member that presses together the over-lapping ends and moves one past the other to contract the loop to the desired extent, a stationary gripper 11 and movable gripper 54 are provided, the latter being eccentrically mounted on a shaft 56 which, when rotated, brings the grippers toward or away from one another. The rotation of the gripper 54 is effected by a helical spring located in a knurled thumb-wheel, the wheel being readily detachable and adjustable relatively to the shaft 56 so as to impart to the spring a desired tension which determines the degree of gripping given to the wire ends. A laterally movable spring latch 80 retains the gripper 54 in its elevated position, and prevents the helical spring from functioning till the latch is manually pressed aside. The wire &c. S, S<SP>1</SP> is then tensioned by repeated oscillation of a lever 43 whereby, through a pawl acting on a ratchet wheel 55 located between the two serrated rims of the gripper 54, a positive rotary motion is imparted to the latter. When sufficiently taut, the wire ends are sealed together by bringing jaws 49 down to and about the overlapped ends by a still further swing over of the lever 43. The lever 43 is then returned, thus raising jaws 49, and the shaft 56 is rotated back against the pressure of the helical spring by turning a handle 64 till the latch 80 reengages. Specifications 289,951, [Class 45], and 354,831 are referred to.

Patent GB-729792-A (GB)
Title: Improvements relating to tank cleaning devices
IPC: B05B3/00
Filed: 1953-01-27
Abstract: 729,792. Cleansing tanks. PYRATE SALES, Inc. Jan. 27, 1953 [Dec. 31, 1952], No. 2315/53. Class 21. [Also in Group XXIX] A spraying device for cleansing tank interiors consists of a turret 20 which rotates about a vertical axis, a nozzle structure 30 thereon which rotates about a horizontal axis, and means for simultaneously driving the turret and nozzle structure about the said axes such that for a substantial whole number of revolutions of the turret the nozzle structure will turn through one revolution plus a small fraction of a revolution. Each stream of cleansing liquid emitted from the nozzle structure is thereby caused to strike the tank walls at a slightly different position on each successive turn of the nozzle structure about the horizontal axis. Liquid, e.g. sea water, is fed to an inlet 13 and passes through slots 29 in a strainer 28 to inclined passages 74 and strikes a turbine 38 having inclined vanes. The turbine drives a shaft 64 which, through worm and worm wheel gearing, drives a shaft 91. A pinion 94, Fig. 5, on the shaft 91 engages a spur gear 95 arranged about a stationary part 11, and a friction clutch holds the spur gear against rotation so that the pinion and the turret rotate about a vertical axis. Simultaneously the shaft 64 drives, through further gearing, a shaft 110. A pinion 115 on this shaft engages a spur gear 49 arranged about a nozzle hub 39, and the hub and nozzle structure, which includes three equally spaced nozzles 35 are therebv rotated about a horizontal axis. The gear chambers 23, 66 and 45 are sealed and contain oil or grease, and bleeder channels 127, 135, 145 drain the spray liquid which may leak from the device. The gearing is such that for each 100 revolutions about the vertical axis the nozzle structure will turn just over one revolution about the horizontal axis, and the nozzle structure does not return to its original starting position with respect to the rotative position of the turret until the latter has completed 7,000 revolutions. The device is supported in the tank by a hose connected at 13 and also by a rope secured to a hanger 17.
